In July 2010, Qosi plead guilty to charges of conspiracy and material support for terrorism before a military commission. His plea was part of a deal in which he agreed to cooperate with prosecutors during his remaining time in US custody. Qosi was transferred to his home country of Sudan two years later, in July 2012.

Qosi joined AQAP in 2014 and became one of its leaders...

A leaked Joint Task Force Guantanamo (JTF-GTMO) threat assessment and other declassified files documented Qosi's extensive al Qaeda dossier. In the threat assessment, dated Nov. 15, 2007, US intelligence analysts described Qosi as a "high" risk to the US and its allies.

"Detainee is an admitted veteran jihadist with combat experience beginning in 1990 and it is assessed he would engage in hostilities against US forces, if released," JTF-GTMO found.

They just released a propaganda video of him, urging, get this, jihad against the west.

Indeed, AQAP's video celebrates jihadists who have acted in accordance with this call, such as the Kouachi brothers, who struck Charlie Hebdo's offices in Paris earlier this year.
